Copper prices fell Monday after China revised its 2017 growth target, throwing doubt on the demand outlook for the world’s key consumer of the industrial metal.

Copper for May delivery settled down 1.7% to $2.6520 a pound on the Comex division of the New York Mercantile Exchange after China cut its 2017 growth target to about 6.5% from last year’s range of 6.5% to 7%.
